Attached below, for your information, is a comparison between the metric and Imperial weight systems.
MyEChef uses metric as it standard weight format for recipe specifications.
You will see the attached table shows metric weights in grammes in column 1.
Column 2 shows the direct pounds and ounces comparison.
Column 3 shows the rounded off metric equivalent for Imperial weights. These are not exact conversions, but approximations, and you will find variations on other sites and cookery books, but you will need to be consistent within your own business to avoid confusion.
Whilst metric is used as the international standard for weight, the UK and USA still use pounds and ounces, as well as “cup” measurements in the US and Canada.
It is important when writing recipe specifications that you use a standard weight format so that your team are not having to jump between, or mixing the two, which may result in poor execution of a recipe specification when being used by a colleague.
